WINDOW-SASH CONSTRUCTION.

Application filed May 10,

This invention relates more specifically to window sashes of the easement type.

An important object of the invention is to provide a novel mechanism for automatically securing the swinging sashes of a casement window into locked engagement with the frame when the same are swung to a closed position, and to provide a construction that will maintain the sashes in wind, dust, and leak proof engagement with the frame when closed. V

A. further object is to provide a swinging window frame construction which will obviate the necessity of employing locking bolts, catches, or similar devices for maintaining the sashes in a closed and locked position. I

A still further object is to provide a sash construction in which it is possible to adjust and lock the swinging sashes in a variety of open positions without the use of additional mechanism.

Briefly, the invention herein shown and described consists in mounting in the sash guide ways of a window frame a' pair of auxiliary frames mounted to move vertically and laterally therein. Hingedly secured to the vertical side bars of the auxiliaryrframes are a pairof window. sashes normally held closed and locked relation to the window frame by the inner window frame sill, the free vertical bars of the swinging sashes being tongued and grooved in order to maintain the sashes in weather proof engagement with each other when closed.

In order to disengage the meeting edges of the sasi-l bars and to raise the lower sash bars free 'of the inner sill when it is desired to swing the sashes to an open position, an operating mechanism is provided for each auxiliary frame and its sash.

Each operating mechanism consists of a disk and link eccentrically attached thereto, the disks being mounted in the outer faces of the inner window frame casings and the links being pivoted to the vertical bars of the auxiliary frames and eccentrically to the disk members, each disk being provided with an operating handle. By the means of the above mechanisms operating one onboth of the auxiliary frames with their sashes may be quickly moved upwardly and laterally to free the sashes from engagement. with each other, and at the same time to clear the upper edge of the inner window sill and 1926.

The invention is especially adapted to be applied to single and double casement windows, but may be .as easily applied to French doors and like structures.

In the drawings and especially. the construction illustrated in Figs. 1 to 5, inclusive, illustrates the construction as applied to a double casement window, which preferably consists of the usual main window frame, including vertical side bars 6, 7, a top plate 8, inner and outer sills 9 and 10, apron 11, vertical inner window casing plates 12, and top casing plate 13, all of usual construction. Secured to the bottom face of top plate 8 and its inner side face lying flush with the side face of plate 8, is a narrow bar 14 to the outer side face of which is secured a flat plate 15, the space between said plate and the top casing plate 13, forming a guide groove 16, for permitting an upward movement of the window sash when it is desired to swing the same to an open position, as will be more fully explained hereinafter. Secured to the oppositely disposed face of vertical side bars 6, 7, are bars 17, 18, similar in form to bar 14, their upper ends abutting against the bar 1-1. Plates 19, 20, similar to plate 15, are secured to the outer faces of bars 17, 18, to form guide-grooves 21, 22, designed to permit of a lateral movement of the sash frames when the same are moved to an open'position.

The method of locking the swinging sashes in the window frame and the mechanism for moving the same into an unlocked position constitutes the important feature of the in vention. In the accomplishment of this object, a pair of movable angular frame members 25, 26, are provided, consisting of upper transversely disposed bars 27, 28, and vertical side-bars 29, 30, joined at their upper ends to the bars 27, 28. These members 25, 26, movably' are disposed in the guide grooves 16, 21, 22, the abutting ends of bars 27, 28 being grooved to form a sealed joint when the windows are closed. Mounted within the opening formed by the angular members 31, disposed on the upper face of sill 10, are a. pair of casementwindow sashes 32, 33, tongued and grooved on their vertical edges, and rabbeted on their upper transverse edges, as at 34, to form weather and dust proof joints. Each window sash on its outer vertical side bar is hinged to the vertical side bars 29, 30, of the movable angular frame members 25, 26. Normally, the movable frame members and swinging sashes are supported on the subsill 31, and as the inside sill 9 is disposed above the upper face of subsill 31, it will be apparent that when the sashes are in closed position they will be securely locked against movement until raised.

Eihould it be found desirable to hold the window sash stationary in a partially open position, as shown in Fig. 16, the disk may be rotated in a direction reverse to that above described for unlocking the sash to permit the lower window sash bar 38, engage with the upper surface of the inner sill 9, the

weight of the sash and movable frame main-- taining the sash against movement after an adjustment.

In Figs. 12 to 141-, inclusive, is illustrated a casement window construction of the tran som type. The sash operating mechanism is connected to the movable frames in exactly the same manner as in the form first described and operates in a like manner. The only change in this form consists in bevelling the engaging surface of the lower transverse bar 50 of the transom 51, and the upper transverse bar 52 of the sash 53 to form a weather proof joint.

It will be understood that the locking mechanism may be as readily applied to a single sash by forming a vertical groove on the window frame adjacent the free verti cal edge of the sash which is provided with a groove engaging tongue.

Each of the vertical bars 29, 30, of the movable frame members are provided with a pair of outwardly extending metal plates 35, rigidly secured thereto, and each plate in its upper portion is provided with an upwardly and outwardly extending inclined slot 36, a headed screw 37, passing through the slot into the bars 17, 18. By means of these connections it will be clear that when the sashes are raised in order to disengage the lower transverse sash bars 38 out of the path of sill 9, that the sashes will be moved transversely or laterally, this movement disengaging the tongue from the grooves formed in the vertical meeting edges of the sashes.

In order to operate the sashes so that they may be swung on their hinges, a lifting mechanism is provided for each window frame, and as both are exactly alike, only one will be described. Rotatably mounted in a circular recess 40 formed on the inner face of inner vertical casing 12, is a circular metal disk 41 provided on its outer face at the center thereof with an operating shaft 42, having d'etachably secured thereto an operating handle 43 for rotating the disk. Eccentrically attached to the disk 11 near its outer edge by a pivot pin :14. is a link 15, the free end of the link being pivotally secured to the outer face of the vertical member 29 of the movable frame 25, the inner face of the disk being provided with a lug 16 adapted to engage with one of the side edges of the link 45 and an extension 4:7 formed thereon, to form a limiting stop when the disk is rotated ineither direction to raise or lower the movable sash frames, and the sashes connected thereto, see Figs. 7 and 9.

From the above description the operation of opening and closing the window sashes will be apparent, assuming the sashes to be in a closed position, as shown in Fig. 1, and it is desired to swing sash 32 to an open position, as shown in Fig. 8, the operator grasps the operating handle 43 and rotates the disk in the proper direction to raise the eccentrically connected link 45, from the position shown in Fig. 7 to the position shown in Fig. 9. This movement will quickly raise the movable frame member 25 vertically, to disengage the sash bar from the sill 9 and the screws 37 that engage in clined slots 36 will simultaneously guide and force the sash 32 transversely to part the tongue and grooves formed on the meeting edges of the sashes. On the completion of this movement, the sash may be readily swung to an open position, the movable frame 25 being held in a raised position by the lug on the disk.

By means of the mechanism above described, the window sashes may be securely locked in weather proof. engagement with their frame, without the necessity of employing bolts or catches. Further, as the sashes snugly fit within the frames, all rattling of the same by driving, wind or other storms is obviated, also it will be apparent that the sashes cannot be opened in any manner from the outside without smashing the glass of the frames.

What I claim is: i

1. In swinging window sash construction, a window frame of usual form including inner and outer sills and top and side guide ways, an auxiliary frame mounted in the guide ways to move vertically and laterally, a swinging sash hingedly secured to said auxiliary frame, said sash when in closed position being locked by the main window frame against movement, and means for moving the auxiliary frame vertically and laterally to disengage the sash from the window frame to permit the same to swing clear of the main and auxiliary frames.

2. A swinging window sash constr etion comprising a window frame of usual form having sash guide ways formed therein, an auxiliary window frame mounted to move in the guide ways, means on said auxiliary frame and movably connected to the window frame for moving said auxiliary frame laterally on a vertical movement of said frame, a sash hingedly secured to said auxiliary frame, and means for moving the auxiliary frame vertically to permit the sash to swing.

In a swinging sash construction, a window frame of usual form including sills and sash guide ways, a swinging sash movably mounted in the frame guide ways and normally locked therein against movement, and

a mechanism for simultaneously moving said sash vertically and transversely of the frame to unlock the sash from the frame and permit the sash to swing out of the frame.

In witness that I claim the foregoing I have hereunto subscribed my name thi 20th day of April, 1926.
